An Automated Grain-shape Classifier

SEPM Journal of Sedimentary Research, 1963
ABSTRACT The velocity acquired by a particle in descending a roughened inclined chute is a measure of three-dimensional particle shape. This principle is embodied in an automatic device for classifying coarse sand grains into three shape classes: spherical, intermediate, and tabular.

Grain-Shape Analysis--A New Method for Determining Representative Particle Shapes for Populations of Natural Grains

Journal of Sedimentary Research, 2005
Abstract The size sorting and shape sorting of gravel bedload by running water often is investigated using identifiable tracer grains that represent the grains within the riverbed. A new, robust, and reproducible method is described for the objective selection of three-dimensional shapes that are representative of the variety of shape within any whole ...

Measurement of Grain Shape Uniformity

Practical Metallography, 2014
Abstract Cold working is well known to change the properties of metals and alloys. Deformation increases the strength of metals but usually reduces its toughness and leads to anisotropy of properties, that is, directionality. Hot working also produces similar affects; the microstructural results after hot work with low finishing ...

Image Analysis of the Shape of Granulated Powder Grains

Journal of Pharmaceutical Sciences, 2004
This study presents and evaluates two new form factors for the characterization of pharmaceutical microparticles using image analysis techniques. The first factor, denoted Vr, is mean percentage variation in radial chord length (for a large number of radial chords drawn at small angular intervals) with respect to mean radial chord length.

Grain-Shaped Control System by Using the SPCA

2003
Recently in the world, noise removable method for images are investigated. This is because it increased to change analog data into the digital style and to use it by the digitization in recent years. Furthermore, when it is changed into the digital style from the analog, it is a cause that noise (impulse element) is made.

Monomineralic metamorphic grain shape

1980
This thesis is concerned with the distribution of faces per grain that results from long term steady state grain growth in a monomineralic granoblastic metamorphic rock.
